Real Time Digital Feedback Control for VFD fed by cascaded multi-cell inverter
(
IEEE
, 2010 , Conference Paper)
Multi-cell inverter include an array of single-phase inverters capable of handling higher voltage ratings with lower rating power electronics devices. In this paper, a Real Time Digital Feedback Controller (RTDFBC) combined ...
A new PLL method for resolvers
(
IEEE
, 2010 , Conference Paper)
This paper describes a novel implementation of the classical PLL closed loop method without using VCO, DAC, counter and look-up tables. The proposed method makes use of the excitation signal of the resolver to estimate the ...

Using low switch converters due to their cost-effectiveness has been an interesting topic in different applications such as grid integration of distributed generation systems and multi-machine drives. Recently, a nine-switch ...
A Comparative Study of High-gain Cascaded DC-DC Converter Topologies
(
IEEE
, 2022 , Conference Paper)
DC-DC boost converters are utilized to step-up the voltage level to match a certain application requirement. Although Conventional boost converter is simple and easy to be implemented, it has a low boosting capability and ...
Space vector pulse width modulation techniques for a five-phase impedeance source and quazi impedeance source inverters
(
IEEE
, 2015 , Conference Paper)
Impedance source inverter (ZSI) and its variant quasi impedance source inverter (qZSI) are single stage inverters that transform dc to ac and boost the source voltage at the same time. These topologies have attracted great ...
